Description
技术领域technical field

背景技术Background technique
多通道超声检测扫查器是使用专用超声检测仪器对平板或管道焊缝进行检测所使用的装置。常规TOFD检测扫查器在管道表面检测时沿管道周向扫查，一般带有一组与焊缝成45度角斜向扫查探头，但对于表面为圆弧面的工件，一旦扫查路径与焊缝不垂直，其扫查探头与检测面无法形成良好的贴合，从而使探头与检测面无法耦合。现在的扫查架，在管道扫查时会沿着管道周向扫查，采用斜向扫查时，一般的斜向扫查结构偏转45度以后无法使探头夹持臂与工件检测面保持垂直，使得探头与检测面无法完全紧贴，影响耦合效果，使检测结果不准确。The multi-channel ultrasonic testing scanner is a device used for testing flat plate or pipe welds with special ultrasonic testing instruments. The conventional TOFD inspection scanner scans along the circumferential direction of the pipeline during the surface inspection of the pipeline, and generally has a set of oblique scanning probes at an angle of 45 degrees to the weld. The welding seam is not vertical, and the scanning probe cannot form a good fit with the detection surface, so that the probe cannot be coupled with the detection surface. The current scanning frame scans along the circumference of the pipeline during pipeline scanning. When using oblique scanning, the general oblique scanning structure cannot keep the probe clamping arm perpendicular to the workpiece detection surface after deflecting 45 degrees. , so that the probe and the detection surface cannot be completely adhered to, which affects the coupling effect and makes the detection result inaccurate.
